Figure 6-12. Active IP method – NX5000
Parameters that must be configured in the Active IP method for the NX5000 Ethernet modules:
IP Address Active: Active PLC communication address. Replaces the IP address from the Non-
Active PLCX;
IP Address PLC A Non Active: PLCA communication address, when in Non-Active state;
IP Address PLC B Non Active: PLCA communication address, when in Non-Active state;
Subnetwork Mask;
Gateway Address.
Multiple IP
The Multiple IP method can be configured in the Ethernet interfaces from the NX5000 Ethernet
modules. In this method there’s an IP for each half-cluster and for each state of the PLC. The PLCA
assumes an IP address when it’s Active and another when it’s Non-Active. The same happens for the
PLCB regarding its state (Active or Non-Active).
